For a while my 2nd gear has been having an issue, when shifting into 2nd gear there is a grind that occurs if not careful when making the shift. When shifting it will feel that the shift has gone in & hear the thud of it going in & then it grinds. Typically when driving I'll put it into 2nd gear & hold the knob in place to be assured that the shift doesn't grind. Not doing half assed shifts when driving but it just seems unusual it grinds like that. All the other gears don't have the same issue I have had with that one. I was told it could possibly be the 2nd gear synchros?
